OmniSTAR Commands (SXBlue II-L GPS)
This section details the commands accepted by the SXBlue II-L GPS to configure and monitor the
OmniSTAR functionality of the receiver. Table 4-5 provides a brief description of the commands
supported by the OmniSTAR built-in sensor for its configuration and control.
Table 5-6 OmniSTAR Commands
Message
Description
$JLBEAM
Request the current spot beam tables in use by the OmniSTAR receiver
$JLXBEAM
Request debug information for the current spot beam tables
$JFREQ
Tune the OmniSTAR receiver either in automatic mode or manually
$JOMS
Request the OmniSTAR engine to provide the current subscription
information for the OmniSTAR service
$JBOOT,OMNI
Allows you to reset the L-band high precision services resolution algorithm
The following subsections provide detailed information relating to the
use of each command.
Note - Please ensure that you save any changes that you wish to survive beyond the current power-
up by using the $JSAVE command and wait for the ‘
$> Save Completed’
response.

$JLBEAM
This command displays the current spot beams used by the OmniSTAR built-in engine. This command
has the following layout:
$JLBEAM<CR><LF>
The receiver will output a first line component (1) and a “multiple second line” component (2) to (n):

The first line (1) of this output is described in the following table:
Data Field
Description
Sent freq1
Frequency (MHz) sent to the digital signal processor
Used freq2
Frequency (MHz) currently being used by the digital signal processor
Baud xxx
Currently used baud rate of the acquired signal
Geo xxx
Currently used satellites longitude (in degrees)
The second line, and those that follow (2) to (n), are described in the following table:
